Advantages of steam activated carbon
Advantages of activated carbon for water purification 1. It can work continuously for 24 hours without shutting down and backwashing, and it has the characteristics of high efficiency. 2. There is no need for a high-lift and large-flow backwash pump, which means that the operating cost of the activated carbon filter is relatively low. 3. During operation, there are basically no rotating parts except the quartz sand filter material, so the failure rate is relatively low, and a large amount of maintenance costs can also be saved. 4. The activated carbon filter does not require a separate coagulation tank, clarification tank, etc., nor does it require backwash pumps, electric and pneumatic valves and other equipment. The amount of engineering is relatively small, and the one-time investment is relatively small. 5. Small head loss: You have a single filter material and the filter material is cleaned in time, so the head loss will be relatively small. 6. It can withstand a certain concentration of water quality for a long time, and can withstand the impact in a short time and keep the water quality unchanged. 7. The filtered water quality is relatively stable, and the filtering effect is relatively good. The filter material is cleaned in a timely manner, which can ensure high-quality and stable water output, and there is no periodic water quality fluctuation. 8. The unit operation mode adopted by the activated carbon filter is to increase or decrease the number of filters flexibly according to the changes in water volume, which is beneficial for modification and expansion. 9. The traditional three-stage reclaimed water treatment process can be integrated, which can save land and make the appearance more beautiful.

What is the carrier of the silica catalyst?
The main advantage is that the chemical properties are relatively stable. It is an acidic oxide and does not react with ordinary acids. It does not interact with halogens, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid other than fluorine and hydrogen fluoride (except for hot concentrated phosphoric acid). If it reacts with the catalyst, it will cause the catalyst to be poisoned. A phenomenon in which the activity and selectivity of the catalyst are significantly reduced or lost due to the trace impurities contained in the reaction raw materials. The essence of the poisoning phenomenon is a certain chemical action of trace impurities and the active center of the catalyst to form inactive species. Secondly, silica has good wear resistance, stable chemical properties, and high melting point. For this reason, using it as the main mineral phase material as the catalyst carrier, its performance is stable. In addition, the treated silicon dioxide has a high specific surface area and strong adsorption, which can increase the catalytic efficiency of the catalyst! In general, the silica carrier has great advantages in terms of catalytic efficiency, catalytic activity, solidity of catalyst loading, service life, and price! Fumed silica (fumed white carbon black) is one of the extremely important high-tech ultrafine inorganic new materials. Because of its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, and dispersion. Good performance, heat resistance, electrical resistance and other aspects have specific performance, with its superior stability, reinforcement, thickening and thixotropy, it is especially advantageous in the catalyst carrier.

Precautions for picking carbon molecular sieves
Precautions for picking carbon molecular sieves Most manufacturers have no significant difference in the carbon molecular sieve in the outer shape, so the user is difficult to distinguish by observing the outer shape of the molecular sieve is difficult to distinguish between imported molecular sieves or domestic molecular sieves. But one thing, if the manufacturer claims to use the high-quality imported molecular sieve, but the price is much lower than the market price, then be careful. It is impossible to sell the equipment without selling the fine. Equipment to buy an in-house domestic molecular sieve is not terrible, but the price of imported molecular sieves has bought domestic molecular sieves, and that loss can be big. We know that using carbon molecular sieve pressure adsorption nitrogen is separated from Van Dehua to separate oxygen and nitrogen, the larger the specific surface area of the molecular sieve, the more uniform the aperture distribution, the more micropores or submicropiles, the amount of adsorption The bigger the more; at the same time, if the aperture can be as small as possible, Van Dehua's field overlaps, there is a better separation of low concentration substances. Therefore, in the PSA nitrogen nitrogen apparatus, the performance of the molecular sieve is directly related to the gas content and energy consumption of the entire device, so that the appropriate adsorbent is the weight.
Market analysis of carbon molecular sieve
Market analysis of carbon molecular sieve For a long time, carbon molecules are sieved into Japan and Germany's monopoly products. The 80% of the domestic markets ago have been posseid in 2000. Carbon molecular sieve technology introduced domestic, domestic carbon molecular sieve manufacturers, mainly distributed in Changxing, Shandong, Xuancheng, and other places. Domestic molecular sieves seized most of the market share, but we must do a strong stronger in this industry, we must innovate, improve product performance indicators, break technology trade barriers. In the next few years, the carbon molecular sieve product will develop in high indicators, high strength, high reactor density, and low-end grade products will be eliminated. The space division equipment will tend to miniaturize, and the molecular sieve industry has put forward higher requirements. Therefore, if you seize the current good time, expand production, gradually change international and domestic awareness of China's production carbon molecules, and quickly seize the domestic international market, it may become an industry drain soldier within two to three years. Domestic market In 2012, the domestic market mainly adopts medium and low-grade carbon molecular sieves. The annual demand is more than 6,000 tons.

Carbon molecular sieve air separation nitrogen production has been widely used in petrochemical equipment, machinery and equipment, metal surface solution, electronic component production and processing, vegetable preservation and other industries. Basic concept of production process Carbon molecular sieve absorption and treatment of organic waste gas is the application of Carbon molecular sieve microplates to digest and analyze the characteristics of chemical compounds, and absorb the organic solvents in the lower concentration of analytical chemical industrial waste gas into Carbon molecular sieve. After purification, the gas after suction and cleaning up to the standard is emptied immediately. The essence is a physical absorption and purification process. The organic solvents are not disposed of. Absorption is the use of the remodeling machinery and equipment produced by our company to melt the organic waste gas caused by the air heating of the organic solvent absorbed in the Carbon molecular sieve to ensure the melting point of the solvent, so that the organic solvent is absorbed from the Carbon molecular sieve And introduce the purified industrial waste gas with a higher concentration value into the catalytic combustion device equipment. The oxidation-reduction reaction of organic waste gas with a higher concentration value in the remodeling machinery and equipment reflects the conversion into harmless water and carbon dioxide into the gas. Absorption can be carried out in addition, using multiple Carbon molecular sieve adsorption beds for adsorption treatment, in addition to one bed for adsorption development prospects, suitable for continuous production and processing sites. Advantages of production process 1. High professional ability to absorb organic molecules in industrial waste gas; 2. High temperature resistant and not easy to corrode; 3. Molecular sieves can be continuously reshaped. The catalytic reaction speed is used to reshape the machinery and equipment to reshape it on time, and the concentrated gas produced in the manufacturing process enters the remolding machinery and equipment and is compounded, resulting in harmless gas sewage treatment and difficult to correct Geographical environment causes secondary pollution; 4. It saves operating costs and does not need to be disassembled on time like activated carbon.
